Application June 12, 1945, Serial No. 599,031

This invention relates to a storm sash carrying a removably mounted screen in the form of a unitary structure to be associated with the usual window closures.

The object of the invention is to provide a screened storm sash of such character that the screen frame may be readily removed and replaced, and the glass plates manipulated in such manner as to permit cleaning or washing the outside of the window from the interior, as well as the inside and outside of the storm sash, this invention being an improvement upon my letters patent granted July 13, 1943, for Sash and ventilator, No. 2,324,139.

Wherein the usual storm sash is mounted in place over a window, it is generally of a rigid structure, requiring removal in the warm months, to be replaced by a screen. It is one purpose of this invention to provide a storm sash embodying a screen removably mounted in connection therewith in such manner that the storm sash may remain in place during the warm months with the full benefit of a screened open window. A feature of the invention in connection therewith resides in the mounting of the screen in the storm sash, such that it may be conveniently mounted in place or removed therefrom.

Furthermore, when the usual storm sash is in place it is not possible to wash the outside surface of the window without completely removing the sash which is difficult, or, at least, inconvenient. By means of this invention the glass plates of the storm sash are so mounted in the frame and in relation with each other, coupled with the removable screen, that they may be readily moved to different positions, such as will permit access not only to their inner and outer surfaces for cleaning, but also the outer surface of the window enclosed thereby, all as will be hereinafter more specifically set forth and described.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Fig, 1 is a central vertical section through a conventional window frame and sash, showing the screened storm sash in place.

Fig. 2 is a front elevation of the screened storm sash.

In the drawings there is illustrated a convenwindow casing, including an inner window sill l5), outer sill I l, outer casing l2 and frame l3. Within the casing there is a window frame in which the lower sash I4 carrying the lower win- 3 Claims. (Cl. 16043) dow pane I5 is slidably mounted, and in the upper portion of the window frame 13 there is slidably mounted an upper window sash IS with an upper window pane I1.

The screened storm sash is removably mount-i ed as a unit within the outer casing of the window to seat upon the outer sill and be secured in place by any suitable means. Said storm sash includes a framework having the vertical frame members I8 joined at the top by a top bar i9 and at the bottom by a bottom bar 20. Intermediate the top and bottom bars and 'secured to the vertical frame members [8 there is a cross bar 2|.

Formed along the inner surfaces of the frame members I8 and extending on each side of the cross bar 2| there is a pair of spaced vertical grooves 22 and 23, each extending in alignment with corresponding grooves formed in the top and bottom bars I9, 20. Slidably mounted in said grooves, respectively, there are glass plates 24 and 25, each of said plates being of a dimension to span one of the openingsdefined by the top bar l9 and the 'cross bar 2! as the upper opening, or the cross bar 2| and the bottombarlll as the lower opening. Said glass plates. are arranged to slide up and down in their respective grooves independently of each other so as to close one of said openings, leaving the other opening open, or close both of said openings as desired. As shown in the drawings both glass plates have been moved to close the upper opening, leaving the lower opening open. Each of said plates slides immediately adjacent, and relative to the cross bar 2|. Thus, when one of the plates is in upper position and the other in lower position, their adjacent edges are sealed by said cross bar.

For supporting the glass plates in their ele vated positions, the vertical frame members are provided with a series of holes 26 along the grooves for receiving supporting pins 21'. Thus, in elevated position, said glass plates rest upon and are supported by said pins at predetermined heights.

For screening the lower opening for protection thereof when both plates are in raised position, as shown, there is provided a screen 28 carried by a frame 29. The upper cross bar of said frame is formed with a recessed block 30 having a horizontal recess 3| to embrace the pins 21 which support the outer glass plate 24. This arrangement is such that when screened ventilation is desired, the outer window plate may be raised to the position shown and supported upon a pair of pins 27. Thereupon the screen may be mounted over the opening by extending at a downward angle in contact with the pins 21 so that said pins lie within the groove 3!. In this position the lower end of the screen is swung inwardly until it seats upon the bottom bar 20, moving the recessed block 30 to embrace and interlock with said pins. The lower end of the screen is then locked in place by removable locking pins 32.

In washing the outside of the windows [5, H, or the glass plates 24, 25 from the interior, it is only necessary to remove the screen by unlocking pins 32 and swinging it outwardly free of the supporting pins 21. Thereupon the glass plates 24, 25 may be freely raised or lowered in conjunction with the raising and lowering of the windows l5, [1, so as to permit a cleaner to reach over or under said windows and plates to clean them.

For example, to clean the outside of the window l1, it is first lowered half way, the glass plates 24, 25 being entirely lowered. By reaching over the top of the window I1, the upper half thereof may be cleaned. By raising the window I5 and raising the glass plates 24, 25, the lower half of the upper window may be cleaned. It will 'be apparent, therefore, that by reason of the readily removable screen and the independently slidable glass plates of the storm sash, access may be had to any and all surfaces of both the window and the storm sash. This makes it possible for all practical purposes to permanently mount a storm sash over a window which will be serviceable in any kind of weather for any desired ventilation and also permit the required cleaning of all parts of the window and sash structure from the interior.

The invention claimed is:

1. A storm sash structure having a rigid frame adapted to be secured in a window casing in storm window relation, the window casing supporting guillotine type windows, said frame having a pair of spaced grooves extending continuously about the interior thereof, a glass plate slidable between raised and lowered positions in one of said grooves, a second glass plate similarly slidable in the other of said grooves, each of said plates extending slightly beyond the center of the frame when in one of said positions so that they will overlap when in opposite positions, a cross bar secured across said frame midway of its upper and lower ends between and adjacent the overlapping portions of said plates to provide a closure therebetween when they are in their respective upper and lower positions, supporting pins removably mounted in said frame in the path of said glass plates selectively to support said plates in raised position, and a screened frame grooved along the top thereof to interengage with a pair of 'said pins to hinge it within said rigid frame, said screened frame being adapted to be swung out of said frame for removal therefrom.

2. A storm sash structure having a rigid frame adapted to be secured in a window casing in storm window relation, 2. pair of glass plates slidable in said frame between raised and lowered positions, each of said plates extending over substantially half of the opening of said frame to leave the lower half of said frame open when both of said plates are moved to the upper half thereof, means for supporting said plates in their upper raised position, at least one of said means comprising a pair of dowel pins removably inserted in said frame to extend inwardly therefrom, and a screened frame adapted to swingably fit within the lower half of said frame and to be removed therefrom said screened frame having a groove provided therein opening from the top thereof for reception of said dowel pins when said screen is entered into said frame at an angle thereto, and interlocking with said pins when said screen is swung to closed position for removably securing it in said frame.

3. In a supplemental storm window and screen structure'for a window opening, the combination of a frame adapted to completely engage the opening thereabout and including two parallel channels in a pair of opposite sides and substantially coextensive therewith, a pair of closures each having a length greater than half the distance between the other two sides and of a width such that the side edges thereof are slidably supported by the channels, seal means carried by the supplemental frame between the channels and extending across the frame and disposed between'the closures at all times, means associated with the channeled portions of the frame for selectively maintaining the closures in adjusted elevations, and an auxiliary screen frame detachably mounted in the frame below the outermost closure and terminating short of the innermost closure supporting channel for innermost closure closing of the screen frame when desired, the outermost closure being adjustable in the frame when the auxiliary screen frame is detached therefrom.
